Abstract (en)

This is to provide a compound that has good solubility in a polar solvent and when it is used as an electrolyte in a catalyst layer of a polymer electrolyte fuel cell, the polymer electrolyte fuel cell exhibits good power generation characteristics.The compound has a structure represented by the following general formula (I)(in the general formula (I), Ar<sup>1</sup> is an aromatic structure optionally substituted by a sulfonic acid group(s), Ar<sup>2</sup> is an aromatic structure optionally substituted by a sulfonic acid group(s), Ar<sup>3</sup> is an aromatic structure optionally substituted by a sulfonic acid group(s), provided that when p=1, Ar<sup>2</sup> is a benzene ring optionally substituted by a sulfonic acid group(s), R<sup>1</sup> to R<sup>5</sup> are each independently hydrogen, a sulfonic acid group or an aromatic group, and the aromatic groups are each independently and optionally substituted by a sulfonic acid group(s), one of R<sup>1</sup> to R<sup>5</sup> is hydrogen or a sulfonic acid group, and four are aromatic groups, one or more kinds selected from the group consisting of Ar<sup>1</sup>, Ar<sup>2</sup>, Ar<sup>3</sup>, R<sup>1</sup>, R<sup>2</sup>, R<sup>3</sup>, R<sup>4</sup> and R<sup>5</sup> when they are aromatic groups and a benzene ring A has one or more sulfonic acid groups, l and m are molar fractions when l+m=1.0, where 0<l≦1.0 and 0≦m<1.0, and when m is not 0, each constitutional unit is randomly copolymerized, "n"s are each independently an integer of 1 to 3, and p is 0 or 1.)
